QUAD/DUAL N-CHANNEL DEPLETION MODE EPAD MATCHED PAIR MOSFET ARRAY

ALD114804/ALD114804A/ALD114904/ALD114904A are monolithic quad/dual N- Channel MOSFETs matched at the factory using ALDs proven EPAD CMOS technology. These devices are intended for low voltage, small signal applica- tions. They are excellent functional replacements for normally-closed relay appli- cations, as they are normally on (conducting) without any power applied, but could be turned off or modulated when system power supply is turned on. These MOSFETs have the unique characteristics of, when the Gate is grounded, oper- ating in the resistance mode for low drain voltage levels and in the current source mode for higher voltage levels and providing a constant drain current. ALD114804 ALD114804A/ALD114904/ALD114904A MOSFETs are designed for exceptional device electrical characteristics matching. As these devices are on the same monolithic chip, they also exhibit excellent temperature tracking char- acteristics. They are versatile as design components for a broad range of Analog applications, such as basic building blocks for current sources, differential ampli- fier input stages, transmission Gates and multiplexer applications.
